Wegovy/Ozempic (semaglutide), Zepbound/Monjourno (trizepitide), etc are the GPL-1 drugs sold today for diabetes and weight loss. Technically they are peptides. So if people you know have "finally" lost a lot of weight, they are likely on peptides.

Peptide manufacture is not as difficult as other drugs because they are injected.

Because the brand names cost a lot, and their manufacture is not too difficult, obviously lots of people got in on the action. Compounding pharmacies, gray market providers, and lots of cheap chinese copies. For one month cost of the name brand you could get many years worth of chinese copies. That is a pretty good hook.

Now that you are injecting one chinese peptide, and it works amazingly well, it is pretty common to check out some of the others. And it is hard to avoid since by the time you find the gray market / chinese suppliers, it is only one of the things they sell.
